Okay, I'll give this a whirl, why not?

1. How did you start gaming?

I got started gaming (RPG's) as a little kid.  No idea when I started playing board games, but that would've been as a really little kid.

2. What system did you start with?

D&D Basic (Red Box - Frank Metzer ed.)

3. What systems have you played?

D&D Basic, D&D Expert, AD&D (1st & 2nd ed.) D&D 3.0, D&D 3.5, D&D 4e, Star Wars (D6/WEG ed.), Star Wars D20, Star Wars Saga ed, Marvel Super Heroes (TSR ed.) the Marvel RPG by Margaret Weis Productions (playtester), Runequest (I have one of the red hardcover copies...), Runequest 2nd ed. Rifts, Dungeon Crawl Classics, Savage Worlds, Gamma World (original & 4e versions),  Wheel of Time (D20 version), Spirit of the Century, MERP, Twilight 2000, Lord of the Rings (ICE & Decipher games editions), Battletech/Mechwarrior (1st, 2nd & 3rd editions) Star Trek (FASA, LUG & Decipher editions).  Various editions different White Wolf games,  Cyberpunk, Shadowrun, DFRPG (of course! and I was on the playtest) and there are at least three other games which I've forgotten the names of, nevermind any other games which I've forgotten that I've played over the years.

4. What system/s are your favorite?  Honestly, the DFRPG

5. Is this your first system?

Not by a long shot.

6. What caused you to try DFRPG?

I'm a big fan of the novels and I really like the setting.  Once I found out about the RPG being in development, I wanted in.

7. What is your preference in gaming group size?

It depends on the game, as well as what's going on, generally 4 - 6 players works best for me.

8. How open are you to gaming with people you don't know or hardly know?

I'm fairly open to it, since I enjoy running DFRPG convention games.

9. What is your best quality as a player?

No idea

10. What is your worst quality as a player?

Not sure, aside from some GM's hate it when I get creative.

11. What is you best quality as a GM?

I can be very creative as a GM.

12. What is your worst quality as a GM?

I can be very creative as a GM.

13. Importance of game balance 1 - 10 (1 being lowest 10 besing highest)

Hard to give a specific number, since what people consider 'balance' can be different

14. Importance of setting/canon of universe 1 - 10 (1 being lowest 10 besing highest)

Setting is a 10, very important as far as I'm concerned.  Whether or not that setting is 'canon' is going to depend a bit on the game and setting.  For my DFRPG campaign, I'm attempting to stick as closely as I can to canon, therefore no one can become another Knight of the Cross, or Summer of Winter Knight, Senior Council member, etc. 

15. Custom setting or established setting?

Depends on the game.  For the DFRPG, established setting.

16. Freedom or concept during character creation? (Powers = Tools?)

Not sure I understand the question.

17. Roll play or role play?  Something inbetween? ( Role playing skills vs dice for resolving things in game)

I don't particularly like roll-playing games, I much prefer running/playing role-playing games.

18. Other: anything notable to volunteer that could explain your view of gaming or your posts on here (obviously mood, upbringing and personality has an affect here, but lets not get too personal eh?)

Honestly, not sure.

Sounds like an aspect to me, maybe with a Linguist stunt or a Mental Library custom power attached.

There's a sidebar somewhere in YS that talks about personified powers. I guess it might be useful here.

I will  have to search for that sidebar.  So far, an Aspect does seem the best way to model this, at least until the entity would have/could have built up its own experiences sufficiently to have knowledge or lore to contribute.

The ability to 'borrow' a stunt like linguist or Medical knowledge is the sort of knowledge sharing I envision the entity would be capable of, once the entity has the chance to gain that knowledge itself.  That is sort of the crux of my dilemma though.

Use of an Aspect and Fate points would provide for the entity being able to perfectly recreate an event as observed from the boy's point of view, mentally projected into the boy's head.  Similarly, if the boy has read a book, the entity knows the contents of the book and can repeat that information back to the boy if/when asked to do so.  The eidetic memory belongs to the entity, not the boy (a subtle distinction, I know...) so therefore things which are repeated are done without any emotional attachment to the event.

Where I see the boy potentially 'borrowing' abilities from the entity would be once the entity has learned a particular language, the entity could translate for the boy.

The key part of the entity being able to translate something would be that the entity would need to become fluent in something before it can translate, it's not a Universal Translator.

The other part of the modeling issue which hasn't really been touched on yet is how the entity should be modeled so that if/when the entity gets passed onto someone else, the things the entity recorded and learned while the boy was it's host can be relayed to its new host.  The biggest difference I would expect after going to a new host, would be that if the new host sees something it doesn't recognize (like a gruff) but the entity would have seen and learned what a gruff while in the boy, the new host could ask the entity what it was and the entity could identify it.

That later sort of interaction would suggest to me that the entity should have its own ranks for the knowledge based skills and/or trappings, which result in the entity having a higher skill rank in some things that its host.

Also, any suggestions on what the entity should be? 

An angel (fallen or otherwise) is out, since they should already have a significant body of information and the entity very specifically does not.  Yet.  The Archive portion of Ivey is sort of what I have in mind, but the boy would be like the very first host of the Archive.  Plus the entity doesn't automatically know whatever gets written down like the Archive/Ivey does.  Not to mention we don't really know much about the Archive itself.  A new or 'baby' Spirit of Intellect that is for some reason seeing refuge and a sanctum in the mortal world is possible, but I don't want the entity to just be another copy of Bob.  Another possibility which occurred to me is that the entity could be a soul, forced out of its body and needing refuge.

-Cheers

One of the characters in the group (specifically a small boy) is going to become the host to an entity.  Think of something like Bob, but before accumulating centuries of experience and lore.  This entity would live within the boy, essentially the boy is its sanctum, and the entity could 'talk' to the boy, much like Lash would do with Harry.

The entity would experience the world through the boy's senses (again, like Lash does with Harry) and similarly be able to 'play back' what the boy saw/heard/smelled/read/etc back to the boy with perfect clarity.

Over time, the entity could accumulate sufficient lore and power to assist its host in things.  Eventually, the entity and all its accumulated knowledge would get passed on to another host.

What I'm trying to figure out is the best way to model this.

So far, I'm sort of leaning towards adapting the Companion rules from Spirit of the Century, but I'd be interested to hear the opinions of others first.

-Cheers

true. I may do that at some point, but I also have limited travelling capabilities cause our cars breaking down lol but whatever works xD

Not to be entirely snarky, about have you tried casting anything?  Breaking computers and cars shows like Mana Static or perhaps a wizard's (un?)natural hexing ability?

-Cheers

Except possibly for the part stating "It must all be cast as one spell."  That seems to disallow multiple wards tied to the same threshold.  It may allow warding an interior room or circle in addition to a house ward.

Actually in the Warrior, Harry has a gun safe which seems to bear some sort of Ward on it as well, which does indeed suggest a Ward-within-a-Ward is possible

 
Which book is this in?  Not ringing a bell at the moment.

In Turn Coat, Harry had a storage facility with a Faraday cage to provide something resembling a weak Threshold.

I think I'd allow the circle but only one per structure/threshold otherwise.

The "LEGO" approach to Wards might be best replicated with a series of individually weak overall Wards which are stronger acting in concert

-Cheers

OK, I was just picturing having and giving a key type item to my friends(aka other PC's) like Harry does for his friends, which brings up a question - does each 'key' cost 2 shifts?  If so that could get expensive quick, so I would probably use a trigger then.

The RAW gives an example on YS277 of a simple condition which adds +2 to the Complexity, but would allow someone to pass through a Ward unaffected as long as they are wearing one of five amulets...  That suggests that something like multiple 'keys' could be setup for only +2, instead of +2 per 'key'.  From a storytelling angle, it would make sense that the 5 'keys' would need to be identical.  Something else to consider when creating 'keys' is whether or not the 'key' will work for anyone holding/wearing/whatever it...  If the keys will work for anyone, then I would say multiple ones could be created for only +2 Complexity.  If the keys will only work for specific people, then I would likely require +2 Complexity per person, and then an additional +2 Complexity if those people need to have a specific 'key' with them to enter.

-Cheers

Maybe I'm missing something, but I'm pretty sure that, once you have the preparations done, you get a roll per exchange to call up and control the power of the spell (at least when time is an issue). This is why Harry can repeatedly quick cast his light weight tracking spell. Things get into the 15 minute range per roll range when some of your preparations are activities taken during the ritual rather than acquisitions made before you even start it. That said, I'd expect most spells to be designed with activities during the spell in mind just so they can reach the necessary complexity without huge amounts of even more time consuming (but also more durable) preparations.

No you have it right, when casting a Thaumaturgy spell you get a roll per Exchange to call up the power and a roll to control that power.  The thing to keep in mind is that an Exchange doesn't automatically correspond to a set period of time.  A combat Exchange for instance might only last a few seconds.  From the novels, a Thaumaturgy spell cast in a hurry should still take about a minute.

The guidelines I use for an Exchange when one of my players is using Thaumaturgy is that if they are taking their time to ensure a successful casting, then each Exchange lasts about 15 minutes and they can automatically succeed in calling up Conviction -2 shifts of power and controlling Discipline -2 shifts of power each exchange, with the player deciding how much power they called up and controlled in a given exchange.  That is usually the lesser of the two.

If the player opts to cast a Thamaturgy or Ritual spell faster, then I would shorten the time of an Exchange down to about a minute per Exchange, but require the player to decide how much power they are attempting to call up and control each Exchange, and requiring the player to roll for success or failure...
